STOVE-B ASE Specification of Letters Patent;

Patented Sept. 22, 1908.

Application filed March 26, 1908. Serial No. 423,299.

To all whom itnnja'y concern:

Be it known that I, JAMES'SHARO a citi- .zen ofthe United States, and a resident of Canaseraga, inthe county of Allegany and State of New York, have invented a new and ImprQve'd'Stove-Base, of which the following and exact description. This invention relates to stove bases. The object of the invention is to provide means for mounting a'stove base ora similar object- .upon casters, the arrangement being such that the casters are normally in a withdrawn or ino erative position, at which time the weight 0 the stove base rests upon the legs. When may be brought into an operative position so that the stove may be moved conveniently.

While the invention is especially useful when applied to stove bases, it is useful in mounting any heavy'objects which are to be moved-at some time.

The invention consists in the construction and combination" of parts, to be more fully described hereinafter and particularly 'set forthv in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference desired, however, the casterslndicate. corresponding parts in all the flgures.

Figure 1 is a perspective'showing-a corner of a stove base constructedaccordmg to my invention; Fig. 2 is a vertical section taken at this corner on the line-2 2 of Fig. '1; Fig. 3 is ahorizontal cross section through a corner of the base and taken on-the line 3-3 of Fig. 2, and Fig. 4 is a erspective of one of theends of the side wal of the"stove base.

Referring more partiularly to the parts, 1 and 2 represent two adjacent side walls or sides of the stove base. At the four corners where the sides of the base are connected together I provide corner posts similar to the corner post 3, so that a rectangular or square base is formed upon which thesto ve bod-yis supported. Theform of the corner post 3 is clearly illustrated in Figs. 2 and 3. It extends downwardly below the loweredges of the sides 1 and 2, so as to constitute a leg which will support the stove base. The stove leg or'post 3 has the form. of a shell, .as indicated in- Fig; 3, its middle portion as viewed in eros s section being curbed, as indicated'at 4. This curbis extended tangentially at the sides to form straight win s 5. These wings are disposed at a wide angle to movable caster block or site edges whereof. are formed with channels or grooves 13, to receive the gulde tongues, as

' end of the block, an

with a bolt head 21,

each other, somewhat less than a right angle, as shown. The ends of the sides 1 and 2 are oflset inwardly so as to present flanges 6, and at each flange 6 a rudimentary socket 1s formed on the outer side. By reason ofthe fact that the flanges 6 are offset inwardly a shoulder or jog 8 is formed at the root of each flange 6, against which the edges of the wings 5 abut as indicated. The corner posts or legs 3 are securely attached to the flanges 6 by means of removable stove bolts 9, as shown. On account of the shell like form of the corner posts v3, in each post a chamber 10- or guide space is formed.

The endsof the flanges 6 are formed with vertically-disposed tongues or guides 11, which project into this chamber or guide space 10, as shown. Between these guide tongues, 11 in-each leg there is mounted a slide 12, the oppomdicated. Each of these blocks 12 has a threaded bore 14 which receives an adjusting screw 15 which extends downwardly through theto wall 16 of the post which is integral with t e shell thereof. Cominunicating with the bore '14 there is a bore 17 of reduced diameter, extending u wardly from the lower in this bore 17 there is mounted the shankor pintl'e 18 of a caster 19.

Il1'cQI1h6ctiI1g the parts, the shank 18 is introduced from below and then a rivet head 20 is formed at its upper end where it proects into the enlarged bore 14', and in this way the caster is" ermaiiently secured to the block, but is swiveled therein, as will be readily understood.

The adjusting screw or bolt 15 is formed which seats on a suitable boss 22 formed on the to wall 16 of a corner post. The adjusting be t is rovided with a collar in the form of a ehec seatsagainst the under side of the upper wall of a leg or post, as shown. In practice, this nut is ammed on the thread at this point so that it will. ermit'free rotation of the adjustin boltfiiut will not permit the adjusting bo t to slide upwardly through the top wall of the leg. V

.The form of the ends of the sides of the stove base is very-clearly illustrated in Fig. 4.

The-sides are provided with upwardly projecting flanges 24,. which match with similar curb flanges 25 on the upper ends of the posts. These flanges match together, as indicated,

nut 23 which so as to form a complete rectangular flange extending continuously around the upper art of the stove base. Over this flan e the ody of the stove seats, as will be readi y understood. Y

7 With a stove base constructed as described, the arts can be quickly assembled, the caster bl dcks being arranged in the corner posts during theassembling of the parts' 1 Especial attention is calledto the fact that the blocks 12 are not guided on the corner posts but on the ends of the sides of thestove base. This'arrangement much simplifies the construction. at. this point and facilitates the assembling of the parts.

Especial attention is called to the fact that the head 21 of the adjusting screw or bolt 15 is exposed and this enables a wrench tobe, very conveniently applied for adjusting the casters. I

In Fig. 2, the dotted lines show the caster in a de ressed position, so that the stove base wi be raised above the floor, enabling it to be readily moved.

' Having thus described my invention, I claim as new and desire to secure by Letters Patent:

. parting a thrust to the said leg.

2. A device having a projecting leg with v substantially vertical guide tongues, a block sliding between said guide tongues, an adjusting screw having an exposed head seated on the upper side of said leg, the body whereof extends downwardly into. said block, said screw afiording means for raising or lowering said block, and a caster swiveled in the lower end of said block. i

3. A stove base having sides, and corner posts connecting the same, caster blocks guided on said sides, adjusting means" for raising or lowering said caster blocks, and casters carried by said blocks andadapted to support said stovebase above the floor.

4. A sto've base having sides, andcorn'er posts connected to said sides, said sides hav ing guide tongues projecting toward the in posts and extending ownwardly into the interior thereof, said adjusting screws engaging said blocks for adjusting the same downwardly or upwardly, and casters carried by said caster blocks, adapted to support the stove base above the 'fioor.

5. A member having a hollow leg with loncally in said leg, saidblock having, a vertical bore passing completely therethrough, an adjusting screw mounted in the upper end of said bore and in the upper end of said leg, and having a head exposed for turning the same, and a caster swiveled in the lower end of said bore. i -6.- A member having a projecting leg, a block guided to slide in said leg and'nonrotatable therein, said block-having a threaded bore in the upper part thereof, an adjusting screw engaging said threaded bore and hav-. ing an exposed head for operating the same, and a caster having a pintle mounted in the lower end of said block and projecting up into said threaded bore, said pintle having means lying in the lower portion of said bore for holding said caster against withdrawal. 7. A member adapted to be supported u ona caster and having a leg presenting a c amber, a block guided in a vertical direction in said chamber and havin a bore in the lower extremity thereof, said bdock having a threaded bore in communication with said first bore and extending to the upper end of saidblock, an adjusting screw mounted in said leg and received in said threaded bore for adjusting said block, and a caster having a pintle mounted in said first-named bore and having a riveted head in the lower part of said threaded bore. v

In testimony whereof I have signed my name to this specification in the presence of 100 two subscribing witnesses.
